Help with receding coral and cauliflower growth

[Justin_C3]

I've got some in my QT that are very unhappy. I see some growth on them that looks like cauliflower. The second picture is an acan and has the cauliflower and an odd looking antenna sprouting everywhere.

My tank parameters are as follows
PH: 7.8 - 8.0
Kh: 10.2
Ca: 500
Mg: 1395
NO3: 10
PO4: 0.03

Any help with treatments or advice?

Thanks

Phosphate at 0.03ppm is really low and if testing was off just a hair, it might be 0ppm which is not a good number for feeding those things, which in turn, feed our corals.

.1ppm would be a better target IMM.

Thanks, I'm currently adjusting the dosing for NeoPhos. I'll up the dose. What are the risks of over dosing? I don't want to go too slow.

I feed the CUC some pellets as this tank has no fish.

The risk would be in corals browning out.
Go slow, test often till you find a number your system likes.
Do everything as normal in terms of feeding and any water changes, the dose is in addition to those things you do.

Make sure you have confidence in your test results.
I do see some green which could indicate higher phosphates than the 0.03ppm, or newer water chemistry.
